I'm a loner, for the most part. Well, I have a husband and two kids, so I only get a chance to be alone when the kids are in school, but I'd love to be alone more often than that. But I love being alone, and never go out of my way to find people to be with. I enjoy my own company, and there are always things to do (alone), which keep me occupied and satisfied.
It would be weird for someone to feel sorry for me. That would be like me feeling sorry for people who always have a group of people hanging around them, and who have to meet someone for coffee every day of the week. I wouldn't want to have to socialize with people every day (or every week, or really even every month), but I don't feel sorry for people who choose to keep people around them all the time.
I do feel sorry for people who desperately want companionship, but, for whatever reason can't find it. That's not a loner, though.
